Changing repeating item

We are running Domino 6.0.2 cf1 on as/400 v5r2. Our users access Domino byWebaccess.

In this problem, Judith has given Bessie rights to edit her calendar:

Bessie is changing Judith’s calendar. When changing a repeating item, she

gets a conflict message. When answering yes, she goes back to the original

item. When she hits save&close, she gets the conflict message…

What can I do to fix this problem?

Thanks,

Jim
